742-05620 742P05620-X 490-110-C188 Toothed Mulching Blades - Fits Cub Cadet 60" Deck, Cub Cadet Ultima ZT2-60 KH FAB ZT3-60 KW FAB ZTS2-60 (3 Pack)

What It Is

This is a 3-pack of toothed mulching blades designed for Cub Cadet 60-inch fabricated decks, specifically the Ultima ZT2-60 KH FAB, ZT3-60 KW FAB, and ZTS2-60 models. They replace OEM part numbers 742-05620, 742P05620-X, and 490-110-C188, and are intended for mulching grass clippings into fine particles for lawn feeding.

Fitment & Compatibility

Before buying, confirm your deck is a 60-inch fabricated (FAB) deck—not stamped. These blades fit Cub Cadet Ultima ZT2-60, ZT3-60, and ZTS2-60 with Kawasaki (KH/KW) engines. Check your current blade’s length (approx. 20.5 inches), center hole diameter (1 inch), and offset; mismatched geometry can cause vibration or poor cut. Aftermarket sets like this are sold as direct replacements but verify your spindle pattern (three-hole or star) matches. Not compatible with 54-inch or 50-inch decks.

Key Things to Know

• Installation difficulty: Moderate—requires a socket wrench, torque wrench (set to 70-90 ft-lbs), and jack stands to safely access the deck. Always disconnect the spark plug first.
• Quality: Most users report good balance and sharpness out of the box, but inspect each blade for burrs or uneven edges before mounting; a few sets have had minor defects.
• Common gotcha: These are mulching blades, not lift blades. They won’t bag or side-discharge effectively. Use only for mulching; swapping modes requires different blade types.
• Wear check: Replace all three at once for even cut. Inspect spindles and belt condition while the deck is off.

Should You Buy It

If you own a Cub Cadet Ultima ZT2/ZT3/ZTS2 with a 60-inch fabricated deck and primarily mulch your lawn, this 3-pack is a cost-effective direct replacement that matches OEM specs at a lower price. Skip it if you bag or discharge often, or if your deck is stamped steel or a different size.
